Non-metallic inclusions usually deteriorate mechanical properties and surface quality of steel products. Presence of non-metallic inclusions might have negative affected some of the mechanical properties of steels like ductility, toughness, anisotropy, and formability. Macroscopic method for assessing the content of non-metallic inclusions in forge...

In conducted research was made a characterisation of microstructure and powder NiCrAlY, before and after applying on the base material. Coating was carried out by using HVOF Diamond Jet procedure, which uses the kinetic energy of the metal particles produced by on explosion of combustible gases. Characterisation was based on chemical analysis of me...

Carburizing is a very popular method of thermochemical treatment to increase the surface hardness of steel parts. It is achived by heating the steel at an austenite temperature in an environment of appropriate carbon source. Carbon sources provide the corresponding so-called a carbon potential (C potential). In the case of equilibrium state, the ca...
